||The endemicity of urinary bladder schistosomiasis and its link with the bladder malignancy
was established in the epidemiological evaluations from across sections of Africa and Eastern Mediterranean.
Notwithstanding, appraisals on the parasite-tumour mergence remained inadequate for most of the Nigerian
communities. This review was to ascertain the pattern in Kano, a colossal city in Northern Nigeria.
This was a 16-year retrospective study from 2nd January, 2001 to 31st December,
2016 of all Schistosoma-ova ingrained bladder cancers cataloged in the Aminu Kano Teaching Hospital,
Kano, Nigeria. The reviewed variables comprised the patient's age, sex and the cancer histopathological
A total of 357 bladder cancers were confirmed during the sixteen year period. Of these, 30 (8.4%)
demonstrated schistosomiasis ova. Patient's age ranged from 26 to 80 years (mean 50.8 ±SD 10.91); the
highest prevalence was the 6th-decade category. Males and females comprised 27 and 3 cases respectively;
the ratio of 9: 1. Squamous cell carcinoma (SCC) was 53.3% of schistosoma-ova positive (SOP) cancers
whilst urothelial carcinoma and adenocarcinoma were 43.3% and 3.3% respectively. The SCCs were mainly
either moderately or poorly differentiated.
This study showed 8.4% bladder cancers had schistosomal ova ingrained and the majorities
were moderately or poorly differentiated SCCs. The review revealed male preponderance plus a peak
prevalence in the 6th decade. The appraisal heightened the need for a further framework in scaling up control
of the risks for bladder cancer including the high burden of schistosomiasis in Nigeria.
